CHEMISTRY HIGH SCHOOL

Most modern forms of transportation are powered by fossil fuels. Carbon dioxide, methane, carbon monoxide, and other gases are released into the atmosphere during the production and combustion of these fuels. How might these gases cause climatic changes? These gases have no effect on atmospheric temperatures, so they are unable to cause any type of climatic changes. These gases cause more water vapor to condense, making climates wetter than they were in the past. These gases reduce the amount of thermal energy escaping into space, effectively warming the atmosphere.

How does the Atomic theory
impact our understanding of the universe?

Answers

Answer:Atomic theory established that all matter is made of tiny particles, a discovery that led to amazing scientific breakthroughs in areas from modern chemistry to nuclear energy.

Explanation:Atomic theory is the scientific theory that matter is composed of particles called atoms. Atomic theory traces its origins to an ancient philosophical tradition known as atomism.

A + B → C Select the rate law for the reaction above using the following information: Holding the concentration of A constant and doubling the concentration of B results in the rate of the reaction increasing from 1.5E-3 M/s to 1.2E-2 M/s. Keeping the concentration of B constant and doubling A results in the rate of the reaction increasing from 1.5E-3 M/s to 3.0E-3 M/s.

Answers

For the initial conditions:
1.5E-3 = k A^n B^m

For the second condition:
1.2E-2 = k A^n (2B)^m
1.2E-2 = 2^m k A^n B^m
From the initial condition:
1.2E-2 = 2^m (1.5E-3)
m = 3.32

For the third condition:
3.0E-3 = k (2A)^n B^m
3.0E-3 = 2^n k A^n B^m
3.0E-3 = 2^n (1.5E-3)
n = 1

Therefore, the rate law is:
r = k A B^3.32

Normal rain has a pH of about 5.5 whereas the most acidic rain measured in Los Angeles had a pH of 1.5. How much more concentrated in H+ is the acid rain than the normal rain?

Answers

pH is used to measure the acidity of a substance and it can be used to calculate the amount of H+ ions in a solution. pH is expressed as:

pH = -log [H+]
For a normal rain:
5.5 = -log [H+]
[H+] = 1 x 10^-5 M

For an acid rain:
1.5 = -log [H+]
[H+] = 0.03 M

the answer is 5.6 !!

Answers

Water, or H2O, is a compound composed of the elements hydrogen (H) and oxygen (O).

What determines the strength of a dipole-dipole force?A. The more symmetrical the molecule, the stronger the force.
B. The more hydrogen in the molecule, the stronger the force.
C. The more polar the molecules, the stronger the force.
D. The larger the atomic radius, the stronger the force.

Answers

The more polar the molecules, the stronger the force. Hence, option C is correct.

What is dipole-dipole force?

Dipole-Dipole forces are the interaction between molecules of the permanent dipole. It occurs between the partially charged positive molecules and partially charged negative molecules.

Polar molecules align themselves so that the δ– end of one molecule is near the δ+ ends of other molecules.

The molecules are thus attracted to each other. Dipole-dipole forces exist between polar molecules.

The greater the polarity, the stronger the dipole-dipole forces.

Hence, option C is correct.

The answer is C: the more polar the molecules, the stronger the force. Hope this helps!

Which element is the most reactive?
sodium, nickel, carbon, or oxygen

Answers

Answer : Option A) Sodium

Explanation : Sodium is the element which is most reactive tin the given options.

Sodium has the atomic number as 11, which is distributed in the atomic shells as 2-8-1.

So, it is clear that the outermost valence shell contains only one electron in sodium. To give away one electron and attain the octet state is easy for sodium. If it donates the electron it becomes a cation which is very reactive, as it gets a positive charge on itself.

Compared to the valency of the other atoms given here, Nickel has 2 valence electrons so it will be less reactive than Sodium.

Carbon has 4 valence electrons which is less than sodium and oxygen needs 2 electrons to be an octet which is also less.
Sodium will be the most reactive as it is a metal lying in the first period and has a valence electron that is readily lost.
